Cas no 6988-39-2 (Methyl 4,6-O-benzylidene-b-D-galactopyranoside)
Methyl 4,6-O-benzylidene-β-D-galactopyranoside is a chemically modified galactose derivative widely used in carbohydrate chemistry and glycosylation research. The benzylidene protecting group at the 4,6-positions enhances regioselectivity in synthetic pathways, enabling controlled functionalization at other hydroxyl sites. Its β-configuration ensures stability and predictable reactivity in glycosidic bond formation. This compound serves as a valuable intermediate in the synthesis of complex oligosaccharides, glycoconjugates, and glycomimetics. Its crystalline form facilitates purification and characterization, while its compatibility with standard protecting group strategies makes it versatile for multistep syntheses. Researchers favor it for its well-defined stereochemistry and utility in probing glycosidase mechanisms or designing bioactive molecules.
